Contacts and telephony

The dialer and the phonebook share a single app although there are two shortcuts, bringing you straight to the tab you need. The app has pleasant flat looks and is about the same as we remember it the last time. The app uses a tabbed interface - recent with dialer on the first and the contact list on the second.

The Phonebook

Xiaomi Mi 4c supports voice call recording and it can do it automatically on each call if you like. You can also assign an answer gesture, pre-define quick responses upon reject, there is even support for internet calling.

The Dialer

There are even more call settings if you dig deeper into the menu - flip to mute the ringer, turn on/off the proximity sensor, lock automatically once slipped in a pocket, it can even mute calls from unknown numbers.

MIUI 7 also introduces Showtime Caller ID - it's a cloud service for Xiaomi owners and you can assign a short video recording to serve as your Caller ID when you are calling other Xiaomi owners. Unfortunately, you have no control over the video Caller IDs you get of other people. If the person who is calling you doesn't own a Xiaomi, or isn't running on MIUI 7 with enabled and configured Showtime Caller ID - this feature will be a no-go.

The Xiaomi Mi 4c scored a Good mark on our loudspeaker loudness test, a notch below the Very Good mark. The produced sound is rather pleasant and deep enough. This means missed calls are unlikely in most environments.

Messaging and email

The messaging department is pretty standard - there's a list of all bubble-styled conversations organized in threads, with New Message and Search keys at the bottom and a settings button next to it.

The Gmail app isn't pre-installed, but you can opt for Gmail or Inbox, if you prefer, from the Play Store. The generic Mail app is capable of handling all kind of mail accounts, including Gmail, and it can handle multiple Exchange, POP or IMAP inboxes. You have access to the messages in the original folders that are created online, side by side with the standard local ones such as inbox, drafts and sent items.

Messaging • Email

MIUI offers Google keyboard by default - it has always been pleasure to use and is one of the most preferred Android keyboards out there. Baidu IME for MIUI is also onboard.

The gallery

The Xiaomi Mi 4c comes with a custom Gallery app, slightly updated since the MIUI 6. It defaults to your camera roll, but it also supports Albums, Cloud and People. The People sorting, once chosen, sorts all of your photos by people's faces. Everything is automatic. Here you can also create a new baby album, to put your newborn pics inside.

Music player

The MIUI music player is a custom app with a well laid out, easy to navigate interface. It features two tabs - the first one is cloud music, similar to Google Music service provided by Xiaomi, while the second tab has your own local and cloud music.

The player has cool effects, transitions and transparent elements, especially on the expandable Now Playing section.

Music Player • Now Playing screen • Lyrics

Xiaomi's Music app offers customizable equalizers with a few default presets already available for use. You can also try Xiaomi's MiSound enhancer, which comes into play when you use headphones, and especially, a Xiaomi-branded headset.

Audio enhancements and equalizers

While Xiaomi Mi 4c comes with a Radio app, it supports only internet stations. There is no FM hardware on the Mi 4c, and it was confirmed by Xiaomi.

Video player

Xiaomi Mi 4c does features a separate video app, which offers a paid video service. Whether you will open your files from the Video app (Local setting) or File Explorer - it doesn't really matter.

The video player interface is very basic but there is rich video codec support. It managed to play everything we threw at it (including MKV and WMV files). The AC3 audio codec is supported too.

Video player

Subtitles and pop-up play are not supported by the MIUI's video player though, so you might want to look around the Play Store if you need a more capable alternative.

Audio quality is nicely clear, averagely loud

The Xiaomi Mi 4c demonstrated perfect clarity when connected to an active external amplifier. Its excellent all-round scores were matched with average volume which is a very good performance for a smartphone in this price range.

Plug in a pair of headphones and stereo quality degrades notably. The good news is this is the only affected thing and the other readings still remain great. Volume doesn't drop either so we are certainly pleased with what we see here.
